How long does the Roost Smart Battery last?

The Roost Smart Battery will typically last 2-5 years in most smoke and carbon monoxide alarms. Its two-piece design includes a replaceable lithium battery and a "smart module" that is reusable.

When your Smart Battery sends you a low-power warning, you can order a Battery Replacement and attach your existing smart module to the new battery. Your Roost Smart Battery should last another 2-5 years.
